HELP PLZ!

Hey!
I’ve been trying to get 100% complete on rdr and I’m stuck at 98%.
I’ve been on the red dead wikia and done everything on the checklist
(Having all outfits, houses, done all hideouts, quests, strangers, won all mini games etc.)
The only outfit I don’t have is the Savvy Merchant Outfit which isn’t on the checklist anyway.
What else can I do?
